Abstract
Process for the preparation of trifluoroethanol by the hydrogenation of trifluoroacetic acid in the liquid phase. The reaction is carried out in the presence of a catalyst based on ruthenium, rhodium, iridium or platinum, under a total pressure of between 5 and 50 bar, and with a ratio of the volume of the liquid phase used in the reactor to the total volume of the reactor of more than about 1/2. An absolute partial pressure of hydrogen of more than 1 bar is maintained during the reaction.
